The fuzzy cylinder theory, originally proposed for conventional polymer solutions, was applied to wormlike micellar solutions to take into account effects of the intermicellar collision and hydrodynamic interaction on the self-diffusion of wormlike micelles in solution at finite concentrations. Previously reported apparent hydrodynamic radius data obtained by dynamic light scattering for non-entangled wormlike micelles formed in aqueous solution by non-ionic surfactants, polyoxyethylene monoalkyl ethers C(i)E(j), were analyzed by this theory to estimate the persistence length q of the wormlike micelles. The results of q estimated were consistent with those obtained from radius of gyration data obtained by static light scattering.
最初为传统聚合物溶液提出的模糊圆柱体理论，被应用于蠕虫状胶束溶液，以考虑在有限浓度下，胶束间碰撞和流体动力学相互作用对溶液中蠕虫状胶束自扩散的影响。此前报道了通过动态光散射获得的非离子表面活性剂聚氧乙烯单烷基醚C(i)E(j)在水溶液中形成的非缠结蠕虫状胶束的表观流体动力学半径数据，利用该理论对这些数据进行分析，以估算蠕虫状胶束的持久长度q。估算得到的q值与通过静态光散射获得的旋转半径数据得到的结果一致。
